UNITED STATES PATENT, OFFICE.

FREDRIOK O. KLIPSTEIN, OF FOND DU LAO, WISCONSIN.

SLED.

SPECIFICATION forming part of Letters Patent No. 279,256, dated June 12, 1883.

Application filedMarch 6,1883. (N0 model.) i

To all whom it may concern Be it known that I, FRnDRroK O. KLIP- STEIN, of Fond du Lac, in the county of Fond du Lac, and in the State of Wisconsin, have invented certain new and useful Improvements in Sleigh-Knees; andI do hereby declare that the following is a full, clear, and exact description thereof. 7

My .invention relates to sleigh-knees; and it consists in certain peculiarites of construction, as will be more fully set forth hereinafter.

In the drawings, Figure 1 is a side elevation of a sleigh-bob embodying my device. Fig. 2 is a vertical cross-section on the line w :v of Fig. 1, and Figs. 3 and 4 are details.

A represents the runner, and B the shoe, of an ordinary sleigh-bob.

O O are metallic plates secured, respectively, to the top and sides of the wooden runner.

D is the standard, consisting of a metallic post (preferably oval in cross-section) shouldered at top to form arectangular tenon, d, to guard against side twist, while its lower portion is enlarged and terminates in two depending pins, d d, the enlarged base being hollow, as shown.

. E is the knee proper, and is cast of metal, and of the general shape shown, although the upper surface may be slightly inclined, if desired, and the cross-beam F similarly shaped to receive it. The knee E has downward-depending flanges e e, which embrace the runners A, (or the protecting-platesG O, secured thereto,) but are not fastened to the said runner, while the top of the knee has a round central hollow flange or ring, 6, and preferably pins 6 e, which project up into mortises made in the under side of the cross-beam F to receive them. This cross-beam is further perforated for the reception of the straight portions of the grips G G, which have hooked lower ends, g, fitting into sockets or holes g in the knee E, While their upper ends are screw-threaded and provided with the nuts in order to 4 secure the knees and cross-beam rigidly together.

H designates one of the raves, which, when made of metal, is preferably formed with two inclined depending legs, H H, but which might of course extend to the forward part of the sleigh, as is usual with the wooden raves now in use, and which is perforated, as shown, to receive the tenon (Z of the standard D, the

lower pins, d d, of which are firmly driven into the runner A, the plate 0 being perforated, when used, to admit them. Thus the runner, post, and rave form one rigid part 011 each side ofthe sleigh, while the knees and cross-beam form another rigid part, and to permit freedom and play of one part against the other the cross-beam is cut away in the center of each end, fore and aft, 011 each side of the standard D, as indicated in dotted lines in Fig. 1, and in the detail view, Fig. 4, while there is very little room for any side play; hence all parts of my sleigh will be firmly united together, and at the same time there will be sufficient play to enable the runners to move considerably up and down without disturbing the boX or body of the sleigh.

The lower part of my knee is concaved or hollowed out between the sockets g and the flanges 6, so as to be less liable to catch and accumulate snow, slush, brush-wood, &c., while above this part the knee is bellied out, so that the hooked ends of the grips can readily slip straight up into their sockets, and thetop of the knee is recessed or grooved in line with the sockets, so that the straight portions of the grips can be held snugly therein, as shown.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is- A 1. The combination of the cross-beam F with the hollow metallic knees E, having circular flange e and pins 6- and sockets g, and the grips G, passing through said crossbeam, and having hooked ends 9, adapted to fit within the said sockets, and nuts to secure the whole rigidly together, as set forth...

2. In combination with the runner, rave, and knee of a sleigh-bob, the standard D, adapted to fit within the knee, and having rectangular tenon (Z on top to prevent side twist, and bottom projecting pins, (1 d, adapt- 95 ed to be driven into the runner, substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand, on this 24th day of February, 1883, in the presence of two wit- 10o IIGSSGS.
